I have sony Bravia klv 32r 412c/2015, with only one hdmi port & no optical audio out port. The hdmi port is connected with fire stick..want to buy bose soundbar 700, is it possible to get audio through the soundbar, from fire stick which is connected with tv .
Specs on that TV show it has 2 HDMI ports and an analog audio output. Doesn't mention ARC so you can't use that.
If the TV does have an analog audio output then you can use the analog audio output of the TV with an analog to optical digital converter. https://www.monoprice.com/product?p_id=8127
If the TV doesn't have analog audio out then get an HDMI input selector with audio extraction. All your sources connect to that with HDMI. The selector HDMI out goes to the TV and the optical audio out goes to the soundbar. You can expand the number of HDMI inputs at the same time.
